Abstract
A curing agent component is useful for a multicomponent epoxide resin composition. An epoxide resin composition produced using the curing agent component, wherein the curing agent component includes, as a curing agent, at least one Mannich base and an amine that is reactive with respect to epoxide groups, as well as at least one polyphenol from the group of novolac resins as an accelerant. The Mannich base can he obtained by reacting a phenolic compound selected from phenol, styrenated phenol, catechol, resorcinol, hydroquinone, hydroxyhydroquinone, phloroglucinol, pyrogallol, o-cresol, m-cresol, p-cresol and bisphenols, with an aldehyde or an aldehyde precursor and an amine having at least two active hydrogen atoms in the molecule which are bonded to a nitrogen atom. The novolac resin is contained in the curing agent component in a proportion of 5-30 wt. %, based on the organic proportions of the curing agent component.
